\( \mathrm{HCl} \) gas is covalent and \( \mathrm{NaCl} \) is an ionic compound. This is because
- A Sodium is highly electropositive
- B Hydrogen is a non-metal.
- C \( \mathrm{HCl} \) is a gas.
- D Electronegativity difference between \( \mathrm{H} \) and \( \mathrm{Cl} \) is less than \( 2.1 \).
Answer & Solution
Correct Answer
(D) Electronegativity difference between \( \mathrm{H} \) and \( \mathrm{Cl} \) is less than \( 2.1 \).
Step-by-step Solution
Detailed explanation
The electronegative difference between \( \mathrm{H} \) and \( \mathrm{Cl} \) is less than \( 2.1 \), therefore, \( \mathrm{HCl} \) gas is covalent compound.
